I have a 2003 4.0 v8 that has started making a ticking/ tapping noise from engine when it gets warm after about 20/30 mins of running. It sounds like a loose tappet but comes and goes. While it's doing it it may last 2 mins then go away for 10mins but when it's there it's quite loud and noticeable. It only seems to do it on idle but I'm not sure if engine noise drowns it out at higher revs.
I've read about all sorts of possibilities from lifters to liners but not sure if my engine has all these thing...
Oil and filter have been changed to see if it made a difference but no luck.
Any ideas before I call the garage?
